Jazz, Laser loads a dxf file up and produces it's own code, it's supposed to be able to load NC files but not played with that.
Once the DXF is loaded you then select what you want to do with each bit by putting them on coloured layers and then you can define speed and power to each colour. Found the DXF on the Vectric site.

Jonathan, will take a more detailed picture tomorrow, got to find it again, think the grand daughters have pinched it, mind you just as quick to cut another one, program is aved on the laser, don't even need a computer connected to it for saved programs.
